Main relationships between the classes

Relationship	n
Class I ∩ Class II	299
Class I ∩ Class III	73
Class II ∩ Class III	37
Class I ∩ Class II ∩ Class III	34

Class I represents susceptibility loci, Class II represents polymorphisms associated with clinical features, Class III represents polymorphisms associated with drug response, ∩ represents intersection. The number of polymorphisms associated with a higher risk of cardiovascular events is not reflected in this table because there are insufficient reports (only 24).
